--- title: Validated Ingredients --- `Ingredient` can be validated based on the three ways you can construct Ingredients * single item * item list * item tag ### Creation ValidatedIngredients are constructed from one of three constructors based on the default type of ingredient ```java !!tabs Java // A validated Ingredient for a single item public ValidatedIngredient validatedIngredientItem = new ValidatedIngredient(Identifier.of("oak_log")); // A validated ingredient accepting a set of items public ValidatedIngredient validatedIngredientList = new ValidatedIngredient(Set.of(Identifier.of("oak_log"), Identifier.of("dark_oak_log"))); // A validated ingredient utilizing a tag public ValidatedIngredient validatedIngredientTag = new ValidatedIngredient(ItemTags.LOGS_THAT_BURN); //get the ingredient from the holder for use in Materials etc public Ingredient validatedIngredientIngredient = validatedIngredientItem.toIngredient(); ``` ```kotlin !!tabs Kotlin // A validated Ingredient for a single item var validatedIngredientItem = ValidatedIngredient(Identifier.of("oak_log")) // A validated ingredient accepting a set of items var validatedIngredientList = ValidatedIngredient(setOf(Identifier.of("oak_log"), Identifier.of("dark_oak_log"))) // A validated ingredient utilizing a tag var validatedIngredientTag = ValidatedIngredient(ItemTags.LOGS_THAT_BURN) //get the ingredient from the holder for use in Materials etc var validatedIngredientIngredient: Ingredient = validatedIngredientItem.toIngredient() ``` ### Usage `ValidatedIngredient` is not an ingredient itself, and does not hold ingredients. It lazily creates ingredients only when needed. This prevents an ingredient from being created before the source for the ingredient is ready (before a tag is populated, for example). Call `toIngredient()` to supply an ingredient. See the documentation page here 🗗
